Abstract Ice hockey helmet standards have primarily been developed to reduce risk of traumatic brain injury (TBI). While severe TBI has become a rare event in ice hockey, concussion, a type of mild TBI, remains a common head injury. Concussions, in ice hockey result from a number of head impact events including, collisions, stick impacts, puck impacts, falls into the boards, impacts to the glass, and falls to the ice. Helmet testing methods need to represent the impact events creating concussions in ice hockey. The purpose of this research was to develop a helmet test protocol and performance metric for concussive impacts in ice hockey. A protocol using concussion impact parameters from published literature was created that used monorail and linear impactors to impact a helmeted Hybrid III headform. The linear and rotational acceleration time curves were then used to calculate brain tissue strain using the University College Brain Trauma Model. The proposed test protocols created kinematic responses that were representative of levels associated with concussion in ice hockey. Rotational velocity and rotational acceleration were both identified as useful performance metrics representing levels of risk for concussion.

成人冰球头盔评估测试方法的开发

摘要 冰球头盔标准的制定主要是为了降低创伤性脑损伤 (TBI) 的风险。虽然严重的 TBI 已成为冰球比赛中的罕见事件，但脑震荡（一种轻度 TBI）仍然是常见的头部损伤。冰球中的脑震荡是由许多头部撞击事件引起的，包括碰撞、棍棒撞击、冰球撞击、掉入板中、撞击玻璃和掉到冰上。头盔测试方法需要代表在冰球中产生脑震荡的撞击事件。本研究的目的是为冰球中的震荡影响开发头盔测试协议和性能指标。创建了使用已发表文献中的震荡冲击参数的协议，该协议使用单轨和线性冲击器来冲击带头盔的 Hybrid III 头型。然后使用线性和旋转加速时间曲线来计算使用大学脑创伤模型的脑组织应变。提议的测试协议创建了代表与冰球脑震荡相关的水平的运动学响应。旋转速度和旋转加速度都被确定为代表脑震荡风险水平的有用性能指标。
